Two ruthenium nitrosyl complexes of Na[RuNOClL] with nitronyl nitroxide radicals coordinated to ruthenium with N-donor pyridine rings were prepared and described. The crystal structure of both complexes is 1D or 2D polymeric, due to the additional coordination of sodium cation by bridging the chloride ligands or oxygen atoms of nitroxides. Partially, the oligomeric forms remain in the solutions of the complexes in acetonitrile. The magnetic measurements in the solid state demonstrate the presence of antiferromagnetic interactions through the exchange channels, with the distance between paramagnetic centers equal to 3.1-3.9 Å. The electrochemical behavior of the prepared complexes was investigated in acetonitrile solutions.
合成并描述了两种钌亚硝酰配合物[RuNOClL]Na，其中硝基氮氧自由基通过吡啶环上的氮供体配位到钌上。由于钠离子通过桥连氯配体或氮氧化物的氧原子与配体配位，两个配合物的晶体结构均为 1D 或 2D 聚合物。在乙腈溶液中，部分配合物以低聚形式存在。固态的磁性测量表明，通过交换通道存在反铁磁相互作用，顺磁中心之间的距离为 3.1-3.9 Å。在乙腈溶液中研究了所制备配合物的电化学行为。
